DEFINITION

This field specifies the function of the message.

CODES

Function must contain one of the following codes (Error code(s): T36):

AMND	Amendment	Replaces a previously sent message with the amended one contained in this message. Used to add settlement agents to an MT 341 previously sent or to correct error(s) in an MT 341 previously sent.
CANC	Cancellation	Cancels a previously sent message. Used to cancel an MT 341 previously sent or to cancel an MT 341 which contains erroneous information.
SETT	New Settlement Confirmation	Used to send the MT 341 for the first time or to send a corrected MT 341 when the erroneous one was cancelled using an MT 341 with function CANC.

USAGE RULES

As the amend message replaces the previously sent confirmation, it must contain both the amended fields and the fields which are not changed.

When the cancel function is used, the message must reconfirm at least the mandatory fields of the original transaction.

An amendment or cancellation message always refers to a previous confirmation.
